To fix the valve, the cardiac surgeon intended to remove the old tissue, resecting the ring-shaped wall of the aorta around it.

If the tongue is exceedingly large compared to the size of the throat, it is reduced by resecting tissue in the midline [Figure 2].

Rubin, M.L., Surgical procedures available for influencing refractive error., in Refractive Anomalies of the Eye. 1966, US Government Printing Office: Washington. Procedures in early literature aimed at shortening the length of the eyeball by resecting a ring of sclera from the equator of the eye.

It changed its name to Busan Research Society of Liver in 1982. Chang's most important research achievements are his study of the liver. His surgical team succeeded in resecting a large amount of liver from a liver cancer patient for the first time in Korea. After eight more liver resection surgeries, they proved that liver resection is not a dangerous surgical procedure.

The Soave procedure involves resecting the mucosa and submucosa of the rectum and pulling through the normal ganglionic bowel through the aganglionic muscular cuff of the rectum. It was introduced in the 1960s and initially did not include a formal join. It depended on scar tissue formation between the pull-through segment and the surrounding aganglionic bowel. The procedure was later modified by Boley.

The surgery of an allograft nerve can be explained in a few steps. First the surgeon has to prepare the broken nerve to do the standard operation procedures. This means the surgeon has to examine the local tissue and resecting scar tissue if needed. The proximal and distal segments of the injured nerves should be debrided to healthy tissue by visual and tactile signs.

When resecting or fixing a position, the geometric strength (angular disparity) of the mapped points affects the precision and accuracy of the outcome. Accuracy increases as the angle between the two position lines approaches 90 degrees.Seidman, David, and Cleveland, Paul, The Essential Wilderness Navigator, Ragged Mountain Press (2001), , p. 100 Magnetic bearings are observed on the ground from the point under location to two or more features shown on a map of the area.

Prior to performing a hemipelvectomy, surgeons must possess detailed knowledge of the pelvic anatomy and its relation to the pelvic tumor. Imaging studies such as conventional radiography, computed tomography, and magnetic resonance imaging help the surgeon visualize the anatomy and its relationship to the local pathology. Surgical oncology techniques are utilized when resecting tumors of the pelvis. Such techniques ensure that adequate resection margins are obtained at the time of surgery to minimize tumor recurrence.

Temporal lobe resection acts as a treatment option for patients with temporal lobe epilepsy, or those whose seizure focus is in the temporal lobe. Temporal lobe seizures are the most common type of seizures for teens and young adults. The procedure involves resecting, or cutting away, brain tissue within the region of the temporal lobe in order to remove the seizure focus. Specific evaluation for temporal lobe resection requires convergent clinical, MRI, and EEG data in order to precisely pinpoint the focal area and boundaries of the focal area.

They then produce pure cultures of lymphocytes that can be tested for reactivity against other tumors, in coculture assays. Individual cultures are then expanded in the presence of IL-2 and excess irradiated anti-CD3 antibodies. The latter targets the epsilon subunit within the human CD3 complex of the TCR. 5–6 weeks after resecting the tumor, up to 1011 lymphocytes can be obtained. Prior to infusion, a lymphodepleting preparative regimen is undergone, typically 60 mg/kg cyclophosphamide for 2 days and 25 mg/m2 fludarabine administered for 5 days.

In 1960 Rob accepted the position of chief of the Department of Surgery at the University of Rochester, Strong Memorial Hospital and moved to the United States. Here, he continued to develop the technique of vein by-pass grafting. In 1961, after recalling that cloth grafts had been used in the aortas of pigs, he used his shirt to successfully repair an aortic aneurysm in a human. After debriding and resecting the aneurysm, the two open ends of the aorta needed to be rejoined with a graft, but the surgeons found that no graft was available to complete the procedure.

In children and young adults with stage IV metastatic rhabdomyoscarcoma, a Cochrane review has found no evidence to support the use of high-dose chemotherapy as a standard therapy. Radiation therapy, which kill cancer cells with focused doses of radiation, is often indicated in the treatment of rhabdomyosarcoma, and the exclusion of this treatment from disease management has been shown to increase recurrence rates. Radiation therapy is used when resecting the entirety of the tumor would involve disfigurement or loss of important organs (eye, bladder, etc.). Generally, in any case where a lack of complete resection is suspected, radiation therapy is indicated.

Pancreatoblastoma is a rare form of neoplasia that develops mostly in pediatric patients. This type of malignant neoplasm mimics pancreatic development at 7 weeks of gestation and tends to afflict, most commonly, young male children. The usual signs and symptoms for this disease are an abnormal abdominal mass, along with abdominal pain or obstructive jaundice, but these symptoms are not necessarily specific for pancreatoblastoma and make the diagnosis a more complicated process (no standardised guidelines). The aggressiveness of the tumors, biologically speaking, makes them often unresectable at the age of diagnosis, therefore requiring other forms of therapy to help shrink the tumor instead of completely resecting it.

Enemy artillery can be detected in two ways, either by direct observation of the guns from the air or by ground observers (including specialist reconnaissance), or from their firing signatures. This includes radars tracking the shells in flight to determine their place of origin, sound ranging detecting guns firing and resecting their position from pairs of microphones or cross-observation of gun flashes using observation by human observers or opto-electronic devices, although the widespread adoption of 'flashless' propellant limited the effectiveness of the latter. Once hostile batteries have been detected they may be engaged immediately by friendly artillery or later at an optimum time, depending on the tactical situation and the counter-battery policy. Air strike is another option.

The breast reduction performed with the free nipple-graft technique transposes the NAC as a tissue graft without a blood supply, without a skin and glandular pedicle. The therapeutic advantage is the greater volume of breast tissues (glandular, adipose, skin) that can be resected to produce a proportionate breast. The therapeutic disadvantage is a breast without a sensitive NAC, and without lactational capability. The medically indicated candidates are: the woman whose health presents a high risk of ischemia (localized tissue anemia) of the NAC, which might cause tissue necrosis; the diabetic woman; the woman who is a tobacco smoker; the woman whose oversized breasts have an approximate NAC-to- IMF measure of 20 cm; and the woman who has macromastia, requiring much resecting of the breast tissues.

It is important to identify the initial trigger sites rather than address all the areas of pain, after the inflammation involves the entire trigeminal tree. Forehead migraine headaches: In the glabellar area the supra- orbital and supra-trochlear nerves are skeletonized by resecting the corrugator and depressor supercilii muscle using an endoscopic approach similar that of used for cosmetic forehead lift. Temporal migraine headaches: The temporal area, where the zygomaticotemporal branch of trigeminal nerve passes through the temporalis muscle, is addressed using a similar endoscopic approach but involves removing a segment of the nerve rather than transecting the muscle. This results in a slight sensory defect over temporal skin area, but cross-innervation from other sensory nerves helps to limit the damage.
